This is where Larsa AI Voice Agents make the difference.
Our AI voice agents answer the phone, talk to callers, collect the information, and instantly send it to your business. You don’t need to write code. Start with one simple use case, like appointment booking, and expand as you go.
What a Larsa AI Voice Agent Does
A Larsa AI voice agent picks up the phone and speaks naturally with callers, just like a human receptionist. It asks questions, listens to responses, saves the details, and then acts on them—whether that’s scheduling a time, sending a confirmation, or updating your database.
Runs on a real phone number
Follows a customized script
Executes actions after the call ends (send emails, update systems, etc.)
Never sleeps, never misses calls, never gets distracted
Typical tasks include:
Appointment scheduling
Service request intake
Lead capture
Basic support
Call transfers
Order taking
Reminders
If the process follows a pattern, Larsa AI can automate it.
Real Example: Booking a Cleaning Appointment
Imagine a home cleaning service getting multiple calls daily. Most callers just ask if there’s availability on a certain day, how long the session takes, or want to book directly.
Instead of a staff member handling the same repetitive process, Larsa AI does it seamlessly:
Greets the caller:
“Hi, thanks for calling FreshSpace Cleaners. Would you like to book a new cleaning appointment or check an existing one?”Guides them through:
Type of service
Preferred date and time
Name and address
Confirmation
Sends a text confirmation automatically
That’s a complete AI-powered receptionist with no human involvement.
What You Need to Get Started
With Larsa AI, setup is simple. You only need three components:
A phone number (via Twilio)
Larsa AI’s no-code voice builder
A place to store the data (Google Sheets, Airtable, Zapier, or your booking tool)
Connect Twilio to Larsa AI, assign a number, create your agent script, and define the information to capture. Once tested, integrate it with your preferred system via webhook or automation.
How Prompts Work
The prompt is at the heart of your agent. It tells the AI what to do—like a job description with clear examples.
For example:
"You are a voice assistant for FreshSpace Cleaners. Your job is to book cleaning appointments. Ask what type of cleaning the caller needs, when they want it, and where. Speak clearly. Confirm all details before ending the call."
Keep it simple. Test and refine as needed.
Capturing Information
Larsa AI lets you extract structured data during calls:
“What’s your address?” → 123 Pine Street
“What day works for you?” → Next Tuesday
“What time?” → 2 PM
These values are automatically stored and sent to your tools—spreadsheets, forms, or booking calendars.
After the Call
When the call ends, Larsa AI can:
Send a text confirmation
Update your CRM or database
Trigger an email
Add rows in Google Sheets or Airtable
Book directly into a system like cal.com
You can also record calls, attach metadata, and review outcomes later.
Outbound Calls with Larsa AI
Voice agents don’t just receive calls—they can also make them. Upload a list of leads, and Larsa AI calls each one automatically.
Example: A home repair business wants to follow up on quote requests. Larsa AI calls each lead:
"Hi, this is Reliable Repairs. You requested a plumbing quote—may I ask you a few quick questions so we can send accurate pricing?"
If the caller agrees, the agent proceeds. If not, the call ends. If human support is needed, the call is transferred instantly.
This allows you to reach dozens of leads in a single day—without manual dialing.
Integrations That Matter
Larsa AI works best when connected with your existing tools:
Google Sheets → save caller data
Zapier → trigger automations
cal.com → live appointment booking
Airtable → structured data management
SendGrid / Twilio SMS → follow-ups
Webhooks → push data anywhere
Where AI Voice Agents Shine
Proven industries where Larsa AI is already working:
Cleaning services
HVAC & plumbing
Medical appointment reminders
Real estate lead qualification
Coaching and consulting
Property maintenance
Auto repair shops
Law firms for intake
Marketing agencies for lead capture
They are less effective in highly unpredictable or emotional conversations. Stick to structured workflows for best results.
Selling AI Voice Agents with Larsa AI
We recommend starting small:
One number
One agent
One task
Typical pricing:
$3,000–$5,000 setup fee
$300–$500 monthly for updates and support
Show a working demo, record a sample call, and business owners will instantly see the value—especially if they receive 10–20 calls per day.
Build Your Own AI Call Center
By combining inbound and outbound agents, you can create a mini AI-powered call center:
One agent answers calls
One agent makes calls
Together, they cover your workflows around the clock—without full-time staff.
With Larsa AI, you don’t need to overbuild. Start simple. Focus on what works. Scale when ready.
